g. 60's, 70's) has put the demand for new items and more efficient energy to an all-new high. These, as everybody knows, are at the bottom of this issue. As usual, a solution for this problem is the industry is very rare due to the businessmen's minds (they believe they need to make money rather than to save earth). There are many different ways to classify air pollutants.
1. Volatile organic compounds (VOCs)* .
2. Particulates .
3. Nitrogen oxides .
4. Sulphur oxides .
5. Carbon monoxide .
6. Ozone .
VOLATILE ORGANIC COMPOUNDS (VOCs).
Volatile Organic Compounds is the closest pollutant associated to coating industries. Emissions of volatile organic compounds contribute to fog. VOC's combine with nitrogen oxides and photo chemically react, due to the sunlight, and produce smog that you can see in some of the biggest major cities across the globe. VOC's are produced and released by a variety of man-made objects and buildings of which the automobile is the biggest contributor. Some of the most common solvents found in paints and coatings are Volatile Organic Compounds. The solvents are released during application and whilst they are being manufactured.
NITROGEN OXIDES.
whilst this class of air pollutant is not released by paint industries; it is another contributor of smog when it is combined with VOC's. These oxides are the results of the combustion of most fuels. This means that most fuel refineries and ore refineries would have a huge Nitrogen Oxide count. Our cars, trains, the heat used to warm our homes up and airplanes are all contributors to the release of Nitrogen Oxides into the atmosphere. .
SULPHUR OXIDES.
Sulphur oxides occur and can be found from the burning of coal/petroleum where sulphur is a natural contaminant. Sulphur oxides can also be found around the area where some ores are burnt. Sulphur Dioxide and Sulphur trioxide are some of the emissions that are made that react with water and produce the acid rain you can find around the world.
